How Soon After Changing Arimidex Dosage Can I Check e2 Levels Accurately?

IIRC, and please correct me if I’m wrong, you need to wait about a month before testing testosterone levels after a change in dose. Is this true of E2 as well or can I check it sooner because it works faster? Thanks.

It will bring E2 down quickly, within a day. Short half-life, about 48 hours. That’s why, if you’re on a 2xwk schedule, the second dose is at 3/3.5 days.

Some, with elevated E2, report feeling differently (better) within hours.

If you are taking T cyp you will reach steady state in 40 days.
What AI are you taking?
Arimidex (Half life 2 days) - Steady state in 10 days
Aromasin (Half life 1 day) - Steady state in 5 days
